No. 154,494. (No specimens.)

To all, whom it may concern:

Be it known that I, AUGUs'rE GAULIN, a citizen of the French Republic, residing in Paris, France, have invented certain new and useful Improvements in Processes of Treating Milk or Similar Liquids; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a partof this specification.

The present invention relates to a process of treating milk and analogous substances to make them keep, 80 that they can be shipped long distances, being a division of my application, Serial No. 125,440, filed September 30, 1902; and it consists in breaking up the larger particles of the constituents of such substances and intimately mixing them preferably, though not necessarily, in connection with sterilization.

5 is a horizontal section of the parts S and W.

Fig. 6 is an elevation of the part W on a larger scale and a portion of the rod 6, having an exaggerated space between them to show that they are independent of one another; and Fig. 7 is a cross-sectional view on an enlarged scale, showing the capillary passages T.

Upon a suitable bed A are pillow-blocks H, in which is journaled' a driving-shaft I, having mounted thereon a fiy-wheel K, a driving-pulley J, and a driving-pinion L. This pinion L meshes with a gear-wheel-M on a-shaft E, journaled in pillow-blocks D on the bed A.

On the shaft E are eccentrics F, whose rods G are connected to cross-heads sliding in the guides C. To the cross-heads are also connectedthe piston-rods 10 of the pumps B. I

have shown by wayofexamplethree ph ps, the eccentrics that drive them being-set at equal angles apart, so that they will :alter- ,i

nately deliver the substance treated and thereby force a continuous stream. The or other liquid to be treated'entersafilter or strainer O by pipe N and then passes throu'gh the pipe g to a reservoir 10, that feeds the several pumpsthrough the inlet-valvesQ. -The pumps then force the milk or other liquid underpressure into the reservoir R, whence itpasses'to the comininuting vessel S on the reservoir.

This vessel S is provided with aplurality of I very fine capillary passages or channelsIT,

that end at a rubbing or squeezing surface,

here shown as a conical surface U] Cooperating with this surface U is ahard blockjor valve W, having a complementary surface V fitting the one U,and that is preferably, though not necessarily. made of agate A easing Y is threaded on or otherwise secured to the part S and provided with a lateral discharge -tube Z for exit of the treated milk or other substance. The end of the-casing Y is provided with a stufling-box a, through which passes a rod Z which is urged by a spring 0 and that abuts on the under face of the agate part W to hold it against the surface U. It will be observed that the agate-partW is provided with facets and the end of the rod 7) adjacent thereto with grooves or ,facets 20 to enable the milk to readily flow to the outlet-pipe Z after being treated.

' The surfaces U and V are exactly fitted to one another by grinding or otherwise andare pressed together by the spring 0, the tension of which is adjustable.

On the rod 6 is a collar 100, against which one end of the spring bears. Passing through cars 11 or equivalent devices are bolts 12, threaded at their ends. These rods pass through a plate d, against which the other end of the spring bears and through which the rod 6 also passes. By suitably moving the nuts 13 on the threaded ends of bolts 12 the tension of the spring can be adjusted. The spring is.a comparatively heavy one to exert a pressure of two hundred and fifty 'to three hundred kilograms per square centimeter, and

even more.

1\/Iounted on the reservoir R 'is a tubular part c, from which leads a discharge-pipef, controlled by a spring-held plunger g, the tension of ,the spring 72 on said plunger being ad- V justed in a manner similar to that described with reference to the spring 0. This arrangement acts as a safety-valve to relieve the pressure in the reservoir R when the pressure therein exceeds a predetermined amount.

At the end of the tube 6 is an air-venting valve 7, of any suitable construction.

The operation is as follows: The milk or other liquid is drawn from the strainer 0, goes by pipe g to the reservoir P to the pumps, which force it under pressure into reservoir R, whence it passes first through the capillary tubes or orifices T, then between the cooperating-surfaces'U V to the outlet-pipe Z. The fat and casein particles in being forced through the capillary tubes or orifices T are either partly broken up or elongated into capillary filaments, and when they. are further forced between the cooperating surfaces U V thecapillary threads of fat and casein are mashed 'or squeezed, so as to completely disintegrate them, thereby producing a'very fine comminution of the coarser constituent particles of the milk, so fine as to prevent them from agglomerating again, and thereby producing a product that will keep for months in the warmest climates.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. The process of treating milk and similar liquids, which consists in elongating the larger constituent particles into capillary filaments, substantially as set forth.

2. The process of treating milk and similar liquids, which consists in elongating the larger constituent particles into capillary filaments and breaking up the filaments thus formed, substantially as set forth.

3. The process of treating milk and similar liquids, which consists in elongating the fat and casein particles into capillary filaments, substantially as set forth.

4. The process of treating milk and similar liquids, which consists in elongating the fat and casein particles into capillary filaments and then squeezing the filaments to break them up, substantially as; set forth.

5. The process of treating milk and similar liquids, which consists in elongating the fat and casein particles into capillary filaments and then breaking up thefilarnents thus formed by squeezing them between capillary surfaces, substantially asset forth. 1

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
